Containment
The containment topic begins with functionality. Can the package be formatted for different forms; can you position a zipper on it? Is it puncture-proof? Creating frameworks that have actually simple tear-offs made to open the container much easier is a must. Consumers also desire a resealable package that is easy to store, and retailers want much better product awareness with 360 degrees of billboard space for branding. Combining that with wanting to preserve the product, the solution comes down to marrying the application and ingredients to the framework.
But the latest innovations for containment are on the inside. The complete framework of flexible packaging includes the following:
The Outside, with graphics, from a matte to shiny metallic, for shelf appeal.
The Barrier (or the capability) to protect the contents from the inside out and the outside in. It can be a standalone part or, in simpler structures, it can be part of the sealant film, adhesive, or extrusion layer. This all depends on how complex the structure is. In one example for snacks, nitrogen gas is used to flush out the oxygen and keep the item from going stale. These barriers are in the film used to make the frameworks. Other products requiring a high moisture barrier will likely have a layer specifically created to protect from moisture intake or exhaling.
The Sealant, which offers the bond strength for the package, can also offer barrier protection in its functionality.
Still, some laminations also supply built-in chemical resistance. These varied packaging structures offer services for more challenging hard-to-hold contents faced by narrow web converters, such as industrial cleaning products, or wellness and beauty items like essential oils or pain relief creams. The demand for higher barrier constructions and chemical resistance while supporting ease of the procedure and lower complete used cost is just beginning. Improved high-barrier laminations enable industrial, automotive, and beauty care products to move into flexible packaging.
